NEET 2014 Physics Adiabatic and Isothermal Processes MCQ Question
Type: MCQ-numerical-Hard-Class 11
A monoatomic gas at a pressure P, having a volume V expands isothermally to a volume 2V and then adiabatically to a volume 16V. The final pressure of the gas is take γ = 5/3
A
64 P
B
32 P
C
P/64
D
16 P
Correct Answer
Option C
Detailed Explanation
The isothermal expansion does not change the pressure ratio, but the adiabatic expansion follows the relation PV^γ = constant, leading to a final pressure of P/64.
